MTP file transfer very unreliable!

[McVitas]

I just don't understand how am I supposed to transfer video recordings from my phone to pc. The transfer using cable is so unreliable it is almost unusable! It is quite fast, but if the video file has size around GB or more, then the transfer usually just hangs in the middle and the folder stops responding and I gotta disconnect the phone, otherwise nothing happens. Are we supposed to buy a MicroSD card reader and keep removing the card from the phone or what?? Using Sony PC companion is no better and behaves the same. It was like this in Windows 8 and now it is the same in Windows 10. Does it work for you? How do you get your 4k recordings out of this phone?

Do you experience the same issue if the videos are stored on the internal storage and you transfer them to your PC?

Do you have Stamnia mode enabled?

And here we go again! I have stamina mode off, phone connected via cable to my pc with windows 10. I try to copy around 10GB of mp4 files from the SD card in the phone. I look at the task manager - it shows hdd write speed around 50MB/s. And after I made myself a tea I notice the remaining time estimation does not change, Xperia Z3 compact windows folder not responding and task manager showing 0KB/s write speed onto hdd! I haven't tried copying from internal memory yet. And I cannot even cancel the operation! After clicking cancel it says "canceling..." forever

Don't try transfer 10GB at a time, try 1 or 2GB

Unfortunately this seems to be a problem of Windows and not entirely tied to the phone. This has happened to me with my old Xperia Acro S, and before that it happened with my Motorola Atrix... and it is a known issue for some Samsung devices.

Luckily I haven't experienced any issues regarding the transferring of files over MTP with my Z3 Compact... but it was something that frustrated me A LOT with my old devices... specially because I also keep some movies inside of them...

In my experience though, the Acro S would usually hang when the last "5 Seconds Remaining" showed in the transfer window, and I would normally wait a little bit longer and then close all explorer windows and unplug... at the end, the phone would have the complete file even if it seemed like it didn't finish. So that's how I managed for months.

If this problem happens to me with the Z3 Compact I will let you know.

The alternative to this is to use a USB OTG cable (instead of extracting the microSD card) and copy the files to a flash drive and then directly from the flash drive to the phone, using File Commander (I recommend file commander because it came preloaded with my device and it has permissions to write on the SD card

even on KitKat).

The other option is to change your connectivity mode to MSC.

Settings > Xperia Connectivity > USB Connectivity > USB connection mode > MSC

If you do this, remember to Safely Remove your device from the computer, before unplugging.

Is your device on Lollipop already?

Thanks for answer! It is easy to say transfer just 1 or 2GB, but one of my movies already has 7GB If you recorded something in 4K you would know. Unfortunately it does not seem to happen before 5 seconds remaining, so I guess it would not work this way. I have the USB OTG reduction (like a very short cable), but it seems it does not work with some bigger flash drives because it probably does not provide enough power to them, so I am not sure I would find some to perform this kind of workaround. I thought MSC is already disabled in Android since KitKat! But I see it was not, so I will test it, thank you! My device is not LolliPop yet
